LT3682IDD#TRPBF

Overview

The LT3682IDD#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range from 3.6V to 36V and provides an adjustable output voltage between 0.8V and 20V. The device delivers up to 1A of output current and features a variable switching frequency ranging from 250kHz to 2.2MHz. Packaged in a 12-WFDFN (3x3mm) exposed pad surface-mount package, it supports operation over a junction temperature range of -40°C to +125°C.

Feature Summary

• Synchronous buck topology for high efficiency
• Adjustable switching frequency for optimization
• Integrated power switch for compact design

Applications

• Industrial control systems
• Embedded computing platforms
• Telecommunications infrastructure

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the DFN-8 package variant matches your PCB footprint requirements. Check official Analog Devices documentation for RoHS compliance status and material declarations prior to final procurement decisions.

Selection Notes

Select this component when a wide input voltage range up to 36V is required alongside moderate current capabilities. The adjustable frequency feature allows designers to optimize for either size or noise performance. Ensure thermal management strategies account for the exposed pad requirement inherent to the WDFN package type.

Part Context

This part belongs to the LT3682 family of synchronous step-down regulators. It shares functional similarities with other Analog Devices PMICs but is distinct in its specific input voltage ceiling and single-output configuration compared to multi-phase or higher-current alternatives in the broader portfolio.

Replacement Considerations

LT3682EDD#PBF is a public confirmed substitute offering identical electrical specifications but in a tube package instead of tape-and-reel.
